==== Usage ====
==== Notes ==== * When the reserved word performs its operation successfully, trendline ID is returned. * When a reserved word cannot perform its operation, it returns an error code.* TL_GetActive should be assigned to a [[Variable|numeric variable]] or [[Array|array]] in order to determine if the operation is performed successfully. In other words, if the returning value of TL_GetActive isn't saved, it's not possible to check whether or not the selection of the trendline succeeded.
==== Example ==== <syntaxhighlight>Value1=TL_GetActive;</syntaxhighlight>
Value1 is any numeric variable or array.
Trendline reserved word should be assigned to a numeric variable or array in order to determine whether the reserved word performed its operation successfully or not.
